Title

(EN) Acidic surfactant composition and method for cleaning wellbore and flowline surfaces using the surfactant composition

Abstract

(EN)

A method and composition for removing deposits of heavy hydrocarbonaceous materials and finely divided inorganic particulate matter from wellbore and flowline surfaces using a composition containing an alkyl polyglycoside, an ethoxylated alcohol, an acid and an alkyl alcohol.
